You are about to begin a titration of an unknown acid of which you have very little sample. YOu added 10.00ml volumetrically to a 125 ml erlenmeyer flask containing 50.0 ml of distilled water, but before you started the titration you realized that you do not have any indicator. Not wanting to waste the expensive sample, you decided to measure the pH of the solution and determined it to be 1.85. What was the concentration of the orginal acid sample? (Hint: it is a monoprotic acid)
What is the pH of the formic acid solution before you begin titrating? b. What is the pH after 50.0 mL of the potassium hydroxide solution has been added?
Assuming the density of water is 1.00g/mL at ambient temperature, what is the exact volume (in mL) of the 250-mL Erlenmeyer flask?
if potassium bromide of 25.5 grams is dissolved in enough H 2 O to make 1750 mL of solution, determine the molarity of the solution?
A certain acid HX is dissolved in water to make a 0.10M solution. At equilibrium, the concentration of X^- ions is 1.0 x 10^-5 M. The Pka of HX is approximately?
Calculate the concentration of H2SO4 if 25.00 mL of the acid is titrated with 41.70 mL of 3.000 M KOH to produce K2SO4 and water
Metal X was plated from a solution containing cations of X. The passage of 48.25 C deposited 31 mg of X on the cathode. What is the mass of X (in grams) per mole of electrons.
A helium-filled balloon has a volume of 2.75 L at 17 C. The volume of the balloon decreases to 2.36 L after it is placed outside on a cold day. What is the outside temperature in K?
Neopentyl alcohol, (CH3)3CCH20H,cannot be dehydrated to an alkene without rearrangement. What is the chief product of dehydration? What product would you expect from addition of deuterium chloride to 2-cyclohexyl-4methyl-2-pentene?
What is the percent yield of lithium nitride if 76.8 g of lithium nitride is recovered from reacting 56.0 g of nitrogen gas with 56.90 g of lithium metal?
If the presure of 50.0 mL of oxygen gas at 100oC increases from 735 mm Hg to 925 mm Hg, what is the final volume? Assume the temperature remains constant.
How many grams of NH4Cl must be added to 424 mL of a 0.69 M solution of NH3 to prepare a pH = 9.00 buffer.
A solution containing Pt4+ is electrolyzed with a current of 5.00 A. How long will it take to plate out 77% of the platinum in 0.50 L of a 0.010 M solution of Pt4+?
